A retired Albany police DARE officer will serve six years in prison for sexually abusing a teenage boy.

Paul Pierce, 59, of East Greenbush was sentenced Friday by Rensselaer County Judge Robert Jacon, who convicted the former officer after a three-day bench trial in April.

The teen victim’s father said in court that his son “suffered sexual abuse from the time he was 15 until he was 17” as a result of interacting with Pierce, a man he trusted.

Pierce will serve four years for one count of third-degree criminal sex act and two years for an additional count of third-degree criminal sex act, both felony charges. The sentences will be served consecutively for a total of six years. A sentencing for child endangerment will run concurrent with the other charges.

Pierce will also serve 10 years of post-release supervision. The judge also signed an order of protection forbidding Pierce from having contact with the victim or his sister until 2036.
